Yosemite upgrade broke ruby.h

Ever since upgrading to Yosemite, I get this error trying to build anything that includes ruby.h:

In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby.h:33:

         ^
1 error generated.

And sure enough, /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby/config.h is indeed missing.

Did the install accidentally a file? Does Yosemite just ship with a busted Ruby header file set?

What's the best way to fix this? Can I just unpack the source code in there to get the right headers?

Did you reinstall the Xcode tools? System upgrades have been known to force that need. – Nickey 17/10, 2014 at 23:16

I reinstalled the Xcode command line tools, but still don't have a ruby/config.h – Rosel 18/10, 2014 at 0:16

I don't think you have the correct Xcode installed. Note the directory in the path: MacOSX10.9.sdk I'd expect to see something about 10.10. – Inkwell 18/10, 2014 at 0:32

CDub! Awesome. I reinstalled Xcode 6.0.1, and now it seems to work, and pulls ruby.h from a completely different location. Thanks for the tip! – Rosel 18/10, 2014 at 16:28

One note on this: I ran into this problem after upgrading to "OS X El Capitan". I installed the command line tools by running 'xcode-select --install'. After that, my ruby build environment started working again.

For those who already had Xcode installed from the Apple developers site, running xcode-select --install doesn't work, since it will say that Xcode is already installed (Xcode already comes with the CommandLineTools bundled).

In my case, I fixed it by downloading the corresponding CommandLineTools from the same place, executing it, then going to /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg and executing it too.

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby
sudo ln -s ../universal-darwin15/ruby/config.h ./config.h

This is not working for me on OS X El Capitan 10.11.6; No such file or directory. I had to run 'xcode-select --install' as described by Jesus instead. – Inception 30/9, 2016 at 19:24

Maybe your MacOSX10.11.sdk or universal-darwin15 needs to be the correct path. It worked for me after ensuring correct path. – Warrior 14/11, 2016 at 6:40

I got the same error, but installed "Command Line Tools (OS X 10.10) for Xcode - Xcode 6.1" and installing worked fine after that.

If you use Homebrew, brew install ruby is a fast workaround (it gets you a brand new ruby installation distinct from the one from Xcode).

@AboozarRajabi echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc if you are on bash or some other shell where you will want to pipe it elsewhere. – Leishaleishmania 7/11, 2018 at 16:43

Thanks, I solved the problem by upgrading Ruby and also Rails to the latest versions (missing gems are reinstalled) – Scholz 7/11, 2018 at 21:15

Wouldn't this potentially break other programs that assume you're using the version that comes with the OS? – Filagree 9/12, 2018 at 3:44

Try this:

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby
sudo ln -s ../universal-darwin13/ruby/config.h ./config.h

Xcode got messed up in the upgrade somehow.

I opened Xcode (which I never do otherwise) and it complained about all sorts of missing components. So I let it go ahead and fix itself, and now all is well.

Props to CDub in the comments on OP for pointing to this as a potential source of weirdness.

I am running Mojave 10.14.6. The answer here fixed the subject issue for me: https://mcmap.net/q/176141/-docker-for-mac-mkmf-rb-can-39-t-find-header-files-for-ruby

Solution:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
sudo xcodebuild -license accept
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

Fixed by pointing to correct path for Xcode developer tools.

Error before (Note the path to Xcode711.app instead of Xcode.app)

/Applications/Xcode711.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/include/ruby-2.0.0/ruby/ruby.h:24:10:

Ran

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
